Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DOIN | input | DO control terminal, used to control the discharge state through an external signal. |
| 2 | COIN | input | CO control terminal, used to control the charge state through an external signal. |
| 3 | TOV | passive | Connect a capacitor to set the overcharge detection delay, Tov = 10^7 x COV seconds (COV typically 0.1 μF). |
| 4 | TOVD | passive | Connect a capacitor to set the overdischarge detection delay, Tovd = 10^7 x COVD seconds (COVD typically 0.1 μF). |
